(Scroll down for video) A newspaper delivery driver found 2 toddlers alone outside while making the daily routine early in the morning, according to police in Saint Louis, Missouri.

Officials from the Missouri Department of Children and Family Services, have visited a house in west St. Louis County, where the two children were found wandering outside early in the morning.

The newspaper delivery driver noticed the two children, ages 2 and 3, just before 5:15 a.m. on the 12500 block of Fee Fee Street.

"The boy had a face of stone, but the girl was crying. Therefore, I lifted her and took her back to the door," Brandon Mueller said.

Both were checked out as a precaution, but are expected to be fine. When police arrived at the scene, they found three men sleeping inside the house.

It is believed that they were responsible for caring for the children, although none of the men is the father of the children and it was not clear what their relationship with the children are. Authorities said that five other children were found in the house.

When police arrived at the house, they also smelled a gas leak. Everyone in the house was then ordered to leave after officials with the gas company found high levels of carbon monoxide.
